Black Magic Intensity Shuttle - no video

Just got my shuttle, and I'm having major issues with it. the main purpose is to stream Wii U games via HDMI. I'm getting audio, and I'm getting pass through video (assuming I have the bmis as source on obs, amarectv, media express etc. working as intended??) But i'm getting no video on the pc side, only audio.

Motherboard is an Asus M5A97 R2.0, with usb3 ports. reinstalled the usb drivers, no help.
